Canada-wide foliage clumping index mapping from multiangular POLDER measurements

Canadian Journal of Remote Sensing, 2005
In this paper, vegetation canopy structural information is retrieved over Canada from multiangular Advanced Earth Observing Satellite (ADEOS-1) polarization and directionality of the earth's reflectance (POLDER) data based on canopy radiative transfer simulations using the Five-Scale model.

Improving GEDI L2B Leaf Area Index Estimation Using a Four-Scale Geometric Optical Model in Temperate Forests

Remote Sensing
LAI is a critical parameter for forest management and global ecosystem monitoring. GEDI provides global-scale vegetation structure data, yet its L2B LAI product often exhibits systematic biases. This study investigates the Maoer Mountain forest in China,

Uncertainty Analysis in the Creation of a Fine-Resolution Leaf Area Index (LAI) Reference Map for Validation of Moderate Resolution LAI Products

Remote Sensing, 2015
The validation process for a moderate resolution leaf area index (LAI) product (i.e., MODIS) involves the creation of a high spatial resolution LAI reference map (Lai-RM), which when scaled to the moderate LAI resolution (i.e., > 1 km) allows for ...

Genetic prediction of blood cell reactivity and its potential causal influence on bone continuity and density disorders

Animal Models and Experimental Medicine, EarlyView.
We applied Mendelian randomization to explore causal links between blood cell traits and skeletal disorders. Using genetic instruments from large‐scale summary statistics, we assessed effects on bone continuity, density, and structural integrity. Sensitivity and reverse analyses confirmed robust associations, highlighting potential shared biological ...

Characterization, validation and intercomparison of Clumping Index maps from POLDER, MODIS, MISR satellite data over reference sites

, 2015
Vegetation foliage clumping significantly alters its radiation environment and therefore affects vegetation growth as well as water and carbon cycles. The clumping index is useful in ecological and meteorological models because it provides new structural

Genetic‐Proteomic Integration Identifies Predictive Plasma Proteins for Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective Multiple sclerosis (MS) develops after a prolonged preclinical phase. Identifying circulating biomarkers that capture this early biology can improve risk stratification and guide intervention. We aimed to identify plasma proteins driving MS susceptibility using large‐scale proteogenomic integration and to evaluate their prediagnostic ...

Impact of Spatial LAI Heterogeneity on Estimate of Directional Gap Fraction from SPOT-Satellite Data

Sensors, 2008
Directional gap probability or gap fraction is a basic parameter in the optical remote sensing modeling. Although some approaches have been proposed to estimate this gap probability from remotely sensed measurements, few efforts have been made to ...

Nanodiamonds as Bioactive Platforms to Modulate Microbial, Mammalian, and Vertebrate Systems

Advanced NanoBiomed Research, EarlyView.
Nanodiamonds (NDs) are biocompatible and antibacterial nanomaterials that support mammalian cell growth while inhibiting bacterial pathogens. NDs showed strong antibacterial activity, with Escherichia coli being more sensitive than Staphylococcus aureus. At 10 mg/mL, both bacteria exhibited ~8% viability.

Advancements in CO2 Capture Technologies: A Review of Amine Absorption and Alternative Methods for Post‐Combustion Integration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Carbon capture technologies are poised to become one of the primary focuses regarding the achievement of net‐zero emissions by the year 2050. In these technologies, particular attention is given to post‐combustion CO2 capture, which is more easily implemented at existing power stations and other industries.

Data synergy between leaf area index and clumping index Earth Observation products using photon recollision probability theory

, 2018
Clumping index (CI) is a measure of foliage aggregation relative to a random distribution of leaves in space. The CI can help with estimating fractions of sunlit and shaded leaves for a given leaf area index (LAI) value.
